wlcore: change way of checking the firmware version
The firmwares version string contain 5 integers. We used to consider
all the digits (except for the first one, which indicates the chip) as
linearly increasing version numbers. This is not correct, because
some of the integers indicate type of firmware (eg. single-role
vs. multi-role) or the internal project it was created for.
Besides, this varies a bit from chip to chip, so we need to make the
firmware version checks more flexible (eg. allow the lower driver to
ignore some of the integers). Additionally, we need to change the
code so that we only check for a linearly increasing number on the
fields where this actually makes sense.

When command timeout happens due to a bug in firmware/hardware,
the timeout handler just prints some debug information. User is
unable to reload the driver in this case.
Inspired by 9a821f5 "libertas: add sd8686 reset_card support",
this patch adds card reset support for SDIO interface when
command timeout happens. If the SDIO host contoller supports
MMC_POWER_OFF|UP|ON operations, the chip will be reset and the
firmware will be re-downloaded.

add Marvell 88W8688 support to libertas_sdio
This chip is for example used in the GuruPlug.
This patch avoids the following error:
libertas_sdio: failed to load firmware
libertas_sdio: probe of mmc0:0001:1 failed with error -5
The fix is based on code in:
drivers/net/wireless/libertas_uap/uap_sdio_mmc.c
This file can for example be found on the following links:

This is pretty pointless. Lets kill this to stop people from
thinking that its actually used. Maybe we should go on
a crusade and kill this completely from the kernel.

rtlwifi: rtl8192ce: rtl8192cu: rtl8192se: rtl81723ae: Turn on building of the new driver
This patch completes the addition of the new driver for the Realtek
RTL8723AE devices by adding the make file and by modifying Kconfig
and Makefile of rtlwifi. Some variable names were shortened to ease
the problem of limiting all lines to 80 characters, thus changes were
made to wifi.h and rtl8192{ce,cu,sw}/hw.c.

Since we have started to use local_amp_id for local AMP
Controller Id it makes sense to rename ctrl_id to remote_amp_id
since it represents remote AMP controller Id.
